Vicious Line of Thunderstorms Moving Rapidly East

I would not be surprised to see a few tornadoes even in the severe thunderstorm watch areas, especially in southern Ohio and southern Pennsylvania. And, if I were in the southern half of Pennsylvania, I would really be battening down the hatches ahead of these storms. Preparatory suggestions here. Please take heed.
